Categorisation of Banks based on level of Computerisation :
Banks may be divided into three board categorises based on the level of computerisation:
Non-computerised banks
Partially Computerised banks
Fully computerised banks
The importance, extent of use and complexity of information systems of each bank may be different than the others. For effectively using a risk-based audit approach, an auditor needs to evaluate the IT risks for a bank before determining the nature, timing and extent of audit procedures.
Special care has to be taken while doing an audit in a fully computerised environment (where the Bank uses Core Banking Solution-CBS).
